Heather Nauert frontrunner to be next U.S. ambassador to the UN

If named Nauert, who met with Trump Monday, would leave her role at the State Department to take over from Nikki Haley, who surprised White House officials last month when she announced her decision to step down at the end of the year.

People close to the President cautioned that his pick is not final until it is formally announced. The White House declined to comment on the matter. Nauert has been keeping a low profile this week after meeting with Trump on Monday. Two of her daily briefings have been conducted by her deputy.
